This has some potential but it's really flat. You're also kinda over-contrasting. The main thing it's lacking is wow-factor though. It's mainly due to the somewhat washed colors and lack of decent lighting transition.

well add a more defined lightsource and work on the bg on the left if not scratch it, it looks lq/oversharpened and thus flat. so like my bro said, give it some depth or maybe do some smudging on the left.
